Abstract (en)
A single pass EP color printer includes a photoreceptor web (146) having multiple layers and including a charge transport layer and a charge generation layer. Four exposure devices (148,150,152,154) (e.g. either laser-based or thin film electroluminescent edge emitting (TFEL) devices) are serially arrayed along the photoreceptor web (146) and act to expose the photoreceptor web (146) in accordance with cyan, magenta, yellow and black color image pixel data. A toner developer module (130,132,134,136) is associated with each exposure device (148,150,152,154) and includes a toner reservoir, a developer roll (138) for carrying the toner to a transfer point. Each developer module (148) is fixed so as to position its developer roll (138) at a constant prescribed distance from the photoreceptor web (146) at the toner transfer point. Erasure devices (158) and charging devices (156) are positioned between the respective developer modules to enable preparation of the photoreceptor web for a subsequent exposure/development operation.
